Drill bit Proline 91030, metal drill, diameter 10 mm, length 300 mm, 1 pc

Proline 91030 single metal drill bit, diameter 10 mm and overall length 300 mm, is designed for drilling metal where extra reach is required. The straight-shank bit is compatible with common hand drills and drill presses and is intended for creating through-holes and general metal fabrication and maintenance tasks at workshops and construction sites.

Advantages

The solid design offers stability during drilling and helps maintain hole accuracy over extended lengths. A specially shaped solid carbide insert at the tip increases wear resistance and provides accurate centered drilling with reduced axial load. The double twist flute geometry promotes efficient chip evacuation and helps maintain drilling speed and performance in professional applications.

Suitable for

• Drilling through-holes in steel and other metals
• Metal fabrication and assembly work
• Maintenance and repair tasks in workshops and construction sites
• Use with hand-held drills and bench or pillar drill presses requiring extended reach

Key specifications

• Diameter: 10 mm
• Overall length: 300 mm
• Shank type: straight shank
• Tip: solid carbide insert for improved durability and centering
• Flute design: double twist for efficient chip removal
• Quantity: 1 piece

How to use

Secure the drill bit firmly in the chuck of a hand drill or drill press, ensuring proper alignment for a straight shank. Select an appropriate drill speed and apply steady, moderate pressure; use cutting lubricant when drilling harder metals to reduce heat and prolong tool life. Withdraw the bit periodically to clear chips if drilling deep holes, and finish using deburring tools if required to remove sharp edges.

Usage recommendations

For best results, use the Proline 91030 with a drill or press that provides stable support and appropriate speed control. Apply cutting fluid when working with high-strength steels, monitor temperature to avoid overheating the carbide tip, and replace the bit when wear affects centering or cutting efficiency.
